' Application and December 2, 1886. Serial No.220,502. (Nomodel) .To aZZ whom, it may concern:

Be it known that-I, CHARLES D. NEEB, of Dexter, in the county of Washtenaw and State of Michigam'have invented certain new and useful Improvements in Cotton or Hay Presses; and I do hereby declare that the following is a full, clear, and exact [description lever.

This invention relates to improvements in cotton or hay presses, and has'specialreference to the means for actuating the compressing-plunger and producing a powerful pressure upon the material in the receiving-box or compressing-chamber.

The invention consists in the construction and novel arrangement of parts hereinafter described and claimed, reference being had to the accompanying drawings by letter.

G designates a portion of the press containing the compressing-chamber g, and having a plunger-block, H, moving in suitable guides, h, adapted to reciprocate in the chainberin the usual manner. These parts of the press may be of any suitable construction, but.

in this instance are similar to those ordinarily used in horizontal presses of this class.

is A designates the framing, which supports the actuating mechanism of the plunger, consisting of two rectangular side frames, a a, suitably connected and braced to give sufficient rigidity to the frame-work when the press is in operation.' The upper and lower timbers of the framing A may be acontinua tion'of the timbers of the compressing-chamber, or. formed separate, if desired. In the latter case, when in operation, the framing A is rigidly connected to the part G by any suitable means.

Near one end of the frame A are located the large gear-wheels B B, each of which is independently journaled or secured to a short shaft, 7), between and on the upper timbers of tween the gears B B, so as to form a crank with i the axles thereof, and which will be more particularly hereinafter referred to.

C designates a shaft journaled in suitable hearings on the frames (1 a. to the inner side of the gears B. Upon the ends of this shaft, outside of the frames, are keyedsimilar gears, C G, and on the inside of the frames upon the shaftO are keyed gears or pinions O O,which engage the gears B B and operate the latter.

.D designates a shaft similarly journaled. upon frames to (6 to t-heinner side of shaft 0,

as'shown, and carrying upon its ends, outside the frames,- the gear wheels or pinions D, which-mesh with the gears O. The shaftDis extended at oneend outside of one pinion D, and has keyed upon it a pulley, d, by which the shaft D is rotated by means of a belt from any suitable source of power.

Shafts O and D may be provided with flyor balance wheels on their outer ends, if desired.

Itis evident that by the arrangement of pinionsand gears described great power is obtained to actuate the gears B B.

E designates a'lever or pitman working between the gears B. The lower end of this lever is pivoted or journaled upon a shaft, E, secured between the lower rails of the frames a a, at the outer end thereof, as shown.

The lever E is provided with a central longitudinal slot, 0, extending from or nearly from its outer or upper end to near its journal on shaft 13'. The slot e is sufficiently long to permit the wrist-pin b to play freely therein, and the lever is made of sufficient width to move securely, but'easily, between the gears B B, and is oscillated upon its pivot by the wrist pin 1) as the gears B B rotate.

To the lever E, about centrally of its length, and to the inner side of the same, is pivotally secured one end of a pitman-rod, F, the other end of which is pivoted to the plunger-block H, as shown. The end of lever B, above rod F, may be recessed, so as to permit the rod to move freely when the lever E is at its lowest position, as hereinafter described.

It is obvious from the foregoing that when the machine is in operation the movement of gears B B will, through the wrist-pin b, oscillate lever E, as described, and that when the pin 1) is farthest away from shaft 0 the plunger is drawn back and the compression-chamber can be filled with material. The gears B B turn toward shaft 0 when in operation, so that when the plunger is retracted, as described, the least power is applied to lever E, the pin being then at the lower portion ofslot 6. When the pin reaches a position nearest shaft 0, it is at the outer end of slot 6, and the plunger is moved inward with great force, as the wrist-pin will then impart to lever E the full power of gears B B, and the plunger will receive the full power of the latter, augmented by the leverage obtained from lever E. It will also be observed that when the plunger is forced inward the leverE is forced downward, and strain is transmitted from plunger H, through rod F and lever E, to the journal of the latter, and the gears thus relieved from undue strain.

I am aware that a system of gear-wheels have been used to impart power to the plunger connected direct to the crank on the shafts of one pair of gears. Therefore I do not claim such construction; but,

Having described my invention, I do claim- 1. In a press, the combination, with a suitable supporting-frame, of a slotted lever journaled at its lower end to the frame, a wrist-pin secured between the two main gears and working in the slot in the lever, as described, said gears, and a pitman pivoted at one end about centrally to the slotted lever, and at the other end to the plunger of the compressing-chamber, and suitable gearing to actuate the main gears, all constructed and operating substantially as described.

2. In a press, the combination of a suitable trainl'of gearing, operated as described and mounted on framing A, with a lever, E, pivoted at its lower end to the lower end of the frame and oscillating between the two main gears of the train, and receiving motion from the same by means of a wrist-pin'moving in a slot in the lever, as described, said wrist-pin, and a pitman, F, connecting the lever and plunger, so as to operate the latter, all substantially as and for the purpose set forth.

3. In a press of the class described, the combination of the gear-wheelsBB, each journaled by a short shaft on the inside of the frame A and operated by a suitable train of gearing, as described, wrist-pin 1), connecting the gears B B, and lever E, pivoted at its lower end to the framing and playing between the gears B B, receiving motion from them through pin 1), working in a slot, e, of the lever, and pitmanrod F, pivoted at one end about centrally and to theinner side of lever E, and at its other end to the plunger of thepress, all constructed and adapted to operate substantially in the manner and for the purposes described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

CHARLES D. NEEB.
